Title: Improvements in or relating to containers having deformable lids
Inventor: KERN EGON
IPC: A47J47/06
Filed: 1968-07-29
Abstract: 1,237,542. Container closures. E. KERN. 29 July, 1968 [27 July, 1967], No. 36077/68. Heading B8T. A food-preserving container comprises a container body, e.g. a bowl 6, and a flexible lid 1 deformable inwardly as shown to apply it to the bowl, and outwardly to close the bowl by means of a handle 5. A skirt 3 on the lid is thereby caused to assume a frusto-conical form. Alternatively, the lid may be curved inwardly in its initial condition and may be deformed outwardly to apply it to the bowl, the skirt then forming a plug fit inside the bowl against which it deforms outwardly when the handle 5 on the lid is pulled up. The lid and the skirt (as shown) or the rim of the bowl may be provided with grooves 7, 8 to facilitate an influx or efflux of air, as the case may be, when the sealing is effected. The skirt 3 or the rim of the bowl may also be provided with ribs 9 to reinforce the seal. The handle 5 may be eccentrically disposed on the lid 1.

Title: A process for preventing deposition of boiler scale and corrosion in heating systems
IPC: C02F1/68
Filed: 1962-09-28
Abstract: Deposition of boiler scale and corrosion in heating systems are prevented by adding to the water an amino-polycarboxylic acid or an alkali metal or hydrazine salt thereof, in amounts more than 0.0001%, and from 0.0001-1.0% of hydrazine.  The actual amount of amino-polycarboxylic acid or salt thereof depends on the amount of salt causing hardness in the water, and the amount of hydrazine is such that there is a small excess always present in the water. The amino-polycarboxylic acid or salt thereof consists of ethylene diamine tetra-acetic acid, nitrilo-triacetic acid, the alkali metal salts thereof or the hydrazine salts of diamine tetraacetic acid; and said acid is capable of forming stable complexes with metal ions. Preferably an excess of 0.1 mg./l. of hydrazine is always present in the water.

Title: Process for the separation and recovery of unsaturated hydrocarbons contained in gaseous mixtures
IPC: C07C7/148
Filed: 1929-12-03
Abstract: <PICT:0350395/IV/1> Unsaturated hydrocarbons contained in gaseous mixtures are converted into their chlorine derivatives and then separated from other constituents by causing the gaseous mixtures together with chlorine to bubble through pipes containing suitable liquids and filling materials, the chlorine derivatives and hydrochloric acid produced being then recovered by condensation and scrubbing from the gases which have taken no part in the reaction. For example, a mixture consisting of hydrogen, nitrogen, carbon monoxide, ethylene, acetylene, and also, if desired, benzene vapour may be treated, the chlorine acting only on the last three constituents to give dichlorethane, tetrachlorethane, and chlorbenzene respectively.  The gaseous mixture may be introduced into a system of U-shaped pipes A filled with iron turnings and containing a liquid such as carbon tetrachloride, tetrachlorethane, or pentachlorethane.  At the foot of the first element of the pipe system chlorine is introduced.  The system is maintained at a suitable temperature, for example, by cooling with water.  The other end of the system A is sealed by a cover B provided with a pipe for the escape of the chlorinated liquid into a vessel C wherein a liquid seal is formed.  A pipe D conveys the residual gases to a separator E in which the chlorine derivatives carried over are condensed and collected.  The gases then pass to a packed column F in which they are scrubbed with water, and thence to a second column G in which they are finally freed from hydrochloric acid and chlorine by means of milk of lime or a dilute solution of caustic soda.  The residual gas is drawn off by means of a fan and conveyed to a gas holder.  The chlorine employed may be 90 per cent electrolytic chlorine.

Title: Improvements in or relating to photographic cameras
IPC: G03B9/07
Filed: 1957-11-29
Abstract: 878,148. Photographic cameras. GAUTHIER G.m.b.H., ALFRED. Nov. 29, 1957 [Jan. 24, 1957], No. 37346/57. Class 98(1) In a camera having an interchangeable lens and a diaphragm which remains fully open up to the moment of exposure and then closes to a pre-determined aperture, the diaphragm aperture pre-setting ring is mounted on the camera and is couplable with a shutter-speed setting ring preferably so that on rotation therewith the speed and aperture are adjusted to each counteract the changes in exposure value produced by the other. As shown, the interchangeable lens, Fig. 2, is mounted on a shutter housing Fig. 1, fixed to the camera body, and diaphragm controlling arm 17 passes through pre-setting ring 14 and engages an abutment 19a on diaphragm opening ring 19. On winding on the film in the camera, ring 19 is operated through shaft 23, gear 22 and toothed segment 19b to open the shutter blades and the diaphragm. The shutter is opened on moving ring 32, which carries the blade pivots, by the co-action of abutment 19c and arm 32a. Ring 19 is thereafter retained by a latch. On releasing the shutter, the latch is released and ring 19 returns under spring 44. Arm 17 is driven by a spring in the lens until it strikes a prepositioned edge of an aperture in ring 14. Ring 14 may be held stationary by latching shutter speed ring 13 to which it is normally coupled on ring 12 which is connected to ring 13 and which controls the shutter mechanism. Rings 13 and 14 are coupled together by means of teeth 13a and an axially slidable member (Fig. 3, not shown) on ring 14. The shutter housing can receive objectives having different maximum relative apertures. The reduced path of movement of arm 17 for lenses of less than the largest possible maximum aperture (from the same starting point 19a) is then accommodated by broadening arm 17 in the direction of its travel (Fig. 5, not shown). Specification 744,962 is referred to.
